Provided is a lubricating oil composition for a differential gear unit that is effective in limiting the generation of noise and vibrations even when a limited-slip differential is operated. The lubricating oil composition contains (A) a mineral oil and/or (B) a synthetic oil and (C) a friction modifier selected from amide- and imide-based friction modifiers and derivatives thereof in an amount of 0.01 to 10 percent by mass on the basis of the total mass of the composition. Also provided is a differential gear unit that is lubricated with the lubricating oil composition.
A lubricating oil composition for a differential gear unit comprising a base oil comprising (A) a mineral oil and/or (B) a synthetic oil and (C) a friction modifier selected from the group consisting of amide- and imide-based friction modifiers and derivative thereof in an amount of 0.01 to 10 percent by mass on the basis of the total mass of the composition.
